Abstract: | To compare the efficacy and safety of fluticasone propionate and zafirlukast in patients with relatively stable persistent asthma who were previously treated with inhaled corticosteroids and short-acting beta(2)-agonists.A total of 440 patients (> or =12 years of age) previously treated with inhaled corticosteroids (beclomethasone dipropionate or triamcinolone acetonide) and short-acting beta(2)-agonists were included in this randomized double-blind study. After an 8-day run-in period, patients were treated with fluticasone (88 microg) or zafirlukast (20 mg) twice daily for 6 weeks. Outcome measures included pulmonary function (forced expiratory volume in 1 second FEV(1)], peak expiratory flow peak flow]), albuterol use, asthma symptoms, withdrawals due to lack of efficacy, and asthma exacerbations.Patients treated with fluticasone (n = 224) experienced greater mean increases in FEV(1) (0.24 L vs. 0.08 L, P <0.001), morning peak flow (30 L/min vs. 6 L/min, P <0.001), and evening peak flow (23 L/min vs. 5 L/min, P <0.001) during the study than did those treated with zafirlukast (n = 216). Fluticasone-treated patients had significantly greater increases in the mean percentages of symptom-free days (22% vs. 8%, P <0.001), rescue-free days (23% vs. 10%, P = 0.002), nights with uninterrupted sleep (<1% vs. -5%, P = 0.006), and fewer asthma exacerbations (1% vs. 6%, P = 0.005). Fewer fluticasone-treated patients were withdrawn due to lack of efficacy (2% vs. 13%, P <0.001).Inhaled fluticasone was more effective than zafirlukast in maintaining or improving asthma control in patients with relatively stable asthma who were switched from low-dose inhaled corticosteroids. |
